PRODUCT INTRODUCTION Thank you for purchasing a Positive Locking Plate Clamp (“plate clamp” or simply “clamp”) made by Vestil Manufacturing Corporation (“Vestil”). Our plate clamps are durable, high-quality products that combine safety features and superior lifting capabilities. Despite the clamp’s relatively simple mechanics, all personnel must familiarize themselves with the safe operation instructions provided in this manual. We produce 3 types of clamp, the LPC-20, LPC-40, and the LPC-60.
SAFETY GUIDELINES Read the entire manual before you use the clamp for the first time and before each subsequent use. Refer to the manual for safe use and maintenance procedures described on p. 7-12. If questions remain after you finish reading the manual, contact Vestil for answers. DO NOT attempt to resolve any problems with the clamp unless you are certain that it will be safe to use afterwards. NEVER modify the product in any way without the express, written approval of Vestil.

Use Instructions: The operating instructions in this manual are meant to supplement the operation recommendations of ASME standard B30.20. Only trained, designated persons should use the plate clamp. “Designated person” means someone selected by his or her employer, or by a representative of the employer, as competent to use the plate clamp. Trainees under the direct supervision of a designated person may use the clamp.
Step 4: Engage the sheet with the clamp. Press down firmly on the clamp until the top of the sheet material contacts the back of the clamp mouth (photo 3a). Lock the clamp by pulling the lock ring and rotating the lock wheel assembly upwards. 4 3a 5 The top of the sheet contacts the back of the clamp mouth (arrow). 3b Step 5: Test the balance of the material in the clamp.
2. DO NOT press down on the sheet material. Grasp ONLY the hoist hook while raising, lowering or moving material to a different location. Your grasp will stabilize the load. 3. Always stand at arm’s length to the side of the material and hold onto the safety hook as shown in photo 7. If you must use two clamps to balance the load, grasp the safety hook that connects plate clamp #2 to the chain adapter. This is demonstrated in the, “Grasp the Safety Hook Attached to the Second Clamp” diagram below.
difficulty, find someone to help you. You should always use the procedures developed by your employer for safely handling material. 10 11 Safety Hook still supports the Shackle Shackle leans to the right Step 9: Disengage the clamp. Pull the latch ring to open the clamp and then rotate the lock wheel assembly downwards. You may need to rotate the connecting link (5) downwards to loosen the gripper (photo 13b). Pull the clamp free of the immobilized sheet; then disconnect the clamp from the hoist hook.
Maintenance and Inspections: A designated person must verify that the clamp complies with all regulations, codes, and standards that apply to “Under-the-Hook Lifting Devices” in the location where the clamp is used. The person(s) designated to conduct inspections by your employer must do so before the clamp is used for the first time, and EACH time it is installed for use. Inspections: The end-user is responsible for performing inspections as recommended in ASME B30.20.
¾ ¾ DO NOT use the clamp if adjustments and/or repairs are incomplete! Return the clamp to service ONLY after finishing all necessary repairs and adjustments. A modification is a change that alters the clamp from normal operating condition, like bending the structural members. NEVER modify the clamp without the express, written approval of Vestil. Modifications may render the clamp unsafe to use. Step 5: Perform a periodic inspection, as recommended in ASME B30.20.
